Hello.
I used CExtTabPageContainerFlatWnd as a base class for custom control. My TabPageContainer contain more one Tab. I need to make some initialize of controls inside container before appearing of form when I did click at tab on the TabPageContainer.
What method of CExtTabPageContainerFlatWnd I need to redefine or make something else?

Dear Artur, Create a class derived from the CExtTabPageContainerFlatWnd class and override this method:virtual bool
CExtTabPageContainerFlatWnd::OnTabWndSelectionChange(
LONG nOldItemIndex,
LONG nNewItemIndex,
bool bPreSelectionTest
)
{
bool bRetVal =
OnTabWndSelectionChange(
nOldItemIndex,
nNewItemIndex,
bPreSelectionTest
);
if( bRetVal )
{
if( bPreSelectionTest )
{
/// POINT A:
/// BEFORE A NEW PAGE BECOMES ACTIVE
/// (the previous page window is still on the top
...
}
else
{
/// POINT B:
/// WHEN THE NEW PAGE IS ACTIVATED
/// (the new page is visible)
...
}
}
return bRetVal;
} As the comments imply, you have two points where you can initialize the page. At the point A you may return false to disable selection of the tab item (this may be useful if your initialization code for this page fails for some reason).
